Speed Limits Matter When Trying to Prevent Serious Accidents

Even a small increase in speed above the speed limit can increase your chance of a crash involving death or serious injury.

2012-05-11

May 11, 2012 (Press-News.org) National measures to curb speeding on local roads and interstate highways have proved to be largely ineffective. In fact, the federal government repealed the national speed limit in 1995, prompting some states to raise their limit as high as 85 mph. Despite all the technology to increase automobile safety and measures to make roads safer, speeding contributes to around one third of the 10,000 traffic fatalities each year, according to AutoGuide.com. A 1998 study estimated the annual economic cost associated with deaths, injuries and damage from speeding was $27.7 billion.

The U.S. Department of Transportation provides guidance to state and local entities to ensure that posted speed limits balance the efficient movement of traffic with the elimination of unnecessary risks. As part of the analysis, unreasonable speed for the conditions significantly increases the risk of an auto accident and the chances of death or serious physical injury in that accident.

An Australian study found that in a 60 kilometer (approximately 37 miles) per hour zone, the chance of a crash involving death or serious injury is twice as likely by driving 65 km (approximately 40 miles) per hour. The risk increases exponentially with each mile per hour above that.

There are several reasons why even slight decreases in speed significantly reduce the risk of serious accident. Higher speeds reduce the time a driver has to react and attempt to avoid a collision. At high speeds and short distances, every second and every extra foot counts. This is particularly true for rear-end collisions where traffic may be at a complete stop and swerving may not be an option.

A shorter available reaction time will result in a higher impact speed due to less time braking. A higher impact speed increases the chances of serious injuries as more energy is transferred from one car to the other. Several tons of metal flying 70 to 80 mph is certainly a potentially deadly weapon, even if the other vehicle is well made.

Obeying posted speed limits is crucial to reducing the risk of accident. The limit takes into account expert opinion regarding road conditions and traffic volume and should be strictly heeded. Since studies show that exceeding the speed limit by even just a few miles per hour can double the risk of an accident, abiding by the limit will keep everyone on the road that much safer.

Systemic sclerosis complications more severe in African Americans than Caucasians

2012-05-11

African Americans have more severe complications from systemic sclerosis, also known as scleroderma, than Caucasians. Findings published today in, Arthritis & Rheumatism, a journal of the American College of Rheumatology (ACR), show that compared with Caucasians, African-American patients were more likely to have antibodies that increased frequency and severity of pulmonary fibrosis, which is associated with decreased survival. According to the ACR there are 49,000 adult American diagnosed with systemic sclerosis—an autoimmune disease where collagen build-ups in the ...

Unseen planet revealed by its gravity

2012-05-11

More than a 150 years ago, before Neptune was ever sighted in the night sky, French mathematician Urbain Le Verrier predicted the planet's existence based on small deviations in the motion of Uranus. In a paper published today in the journal Science online, a group of researchers led by Dr. David Nesvorny of Southwest Research Institute has inferred another unseen planet, this time orbiting a distant star, marking the first success of this technique outside the solar system. Using a laborious computational method to assess the effects of gravity, known as gravitational ...

Breathalyzers in Colorado

2012-05-11

Everyone has heard about them. Whether one has seen them on television or in driver's education classes, every driver is aware that police officers use an Intoxilyzer or other breath test device as a tool to determine if a driver is operating a vehicle while under the influence of alcohol. Yet, many drivers have questions about these devices. Are we required to submit to a Breathalyzer test? How do these devices work? How many kinds are there? Are they accurate? People may ponder these questions at one time or another, but they rarely stop to think about the answers. ...

HPV-positive throat cancer patients respond better to radiotherapy alone than HPV-negative patients

2012-05-11

Barcelona, Spain: New findings from a large Danish database of cancer patients suggest that, even though the human papilloma virus (HPV) can trigger throat cancer, patients who are HPV-positive and are light smokers, or don't smoke at all, have a good response to treatment using radiotherapy alone, without the addition of chemotherapy with its consequent toxic side-effects. Presenting her research at the 31st conference of the European Society for Radiotherapy and Oncology (ESTRO 31) [1] today [Thursday], Dr Pernille Lassen, a resident in medical and radiation oncology ...

The Police Are at Your Door. Do You Know What to Do?

2012-05-11

"Trust me; things will be a lot easier if you cooperate." These words -- or something like them -- are spoken by countless law enforcement officers every day. They're true, but only in part: things will be a lot easier for the police if you give them what they are asking for. However, if you are suspected of a crime, asserting your rights at the early stages of the investigation is the most important step you can take to protect your future. If you suspect that you may be under investigation, be polite, but don't give the police access to any information ...

3-D image guided brachytherapy helps avoid hysterectomies for cervical cancer patients

2012-05-11

Barcelona, Spain: Delivering radiotherapy directly to cancer of the cervix using 3-D imaging techniques is effective at controlling the return and spread of the disease and, in most cases, avoids the need for hysterectomies, according to research presented at the World Congress of Brachytherapy [1 & 2] today (Thursday). Dr Renaud Mazeron said that a review of the use of 3-D image guided adaptive brachytherapy (IGABT) after a course of chemotherapy and radiotherapy given together (concomitant chemoradiation) in 163 patients treated between 2004-2009 at the Institut Gustave ...

New IBEX data show heliosphere's long-theorized bow shock does not exist

2012-05-11

New results from NASA's Interstellar Boundary Explorer (IBEX) reveal that the bow shock, widely accepted by researchers to precede the heliosphere as it plows through tenuous gas and dust from the galaxy does not exist. According to a paper published in the journal Science online, the latest refinements in relative speed and local interstellar magnetic field strengh prevent the heliosphere, the magnetic "bubble" that cocoons Earth and the other planets, from developing a bow shock. The bow shock would consist of ionized gas or plasma that abruptly and discontinuously ...

Divorce & Stock Options: Valuations, Exercised Options and Taxes Oh My!

2012-05-11

Property distribution in divorce is difficult even in simple estates, but complications abound for those with more complex mixes of assets. These high-asset divorce cases often require review of financial portfolios, including stock options. Stock options are often used to lure key employees into high-level positions. A stock option is a contract that allows the holder to purchase a specified amount of stock for a certain price within a set time period. Stock options can be provided as an additional form of compensation and offer an incentive not only to continue working ...

Large Trucks Pose Heightened Risks to Oklahoma Drivers

2012-05-11

Commercial trucks are -- quite literally -- some of the largest hazards on Oklahoma's roads. A fully loaded semi truck can weigh up to 80,000 pounds. By comparison, the average passenger vehicle weighs a mere 4,000 to 5,000 pounds. In a collision between the two, the truck almost always comes out on top. This disparity in size makes truck accidents considerably more deadly than other types of motor vehicle collisions. Although large trucks account for just 4 percent of all registered vehicles and 7 percent of all vehicle miles driven, they are involved in 11 percent ...

Asteroid collision that spawned Vesta's asteroid family occurred more recently than thought

2012-05-11

A team of researchers led by a NASA Lunar Science Institute (NLSI) member based at Southwest Research Institute has discovered evidence that the giant impact crater Rheasilvia on Asteroid (4) Vesta was created in a collision that occurred only about 1 billion years ago, much more recently than previously thought. This result is based on the analysis of high-resolution images obtained with the Dawn spacecraft, which entered orbit around Vesta in July 2011. In addition to creating the crater, the impact is believed to have launched a large number of fragments into space, ...
